About Us

We are a group of domestic and international non profit organizations working in Canada to reduce oil and gas methane emissions through rigorous science, policy, advocacy and legal expertise. Collectively, we represent millions of members across North America calling on global action to tackle methane emissions from the oil and gas industry.


David Suzuki Foundation

The David Suzuki Foundation is a leading Canadian environmental non-profit organization, founded in 1990. We operate in English and French, with offices in Vancouver, Toronto and Montreal. We collaborate with all people in Canada, including First Nations leadership and communities, governments, businesses and individuals to find solutions to create a sustainable Canada through scientific research, traditional ecological knowledge, communications and public engagement, and innovative policy and legal solutions. Our mission is to protect nature’s diversity and the well-being of all life, now and for the future

Pembina Institute

The Pembina Institute is working to solve today’s greatest energy challenges – reducing the harmful impacts of fossil fuels while supporting the transition to an energy system that is clean, safe and sustains a high quality of life. We provide our expertise to industry and government leaders, and we advocate for a strong, science-based approach to policy, regulation, environmental protection, and energy development.

David McCabe

Senior Scientist, Clean Air Task Force

David McCabe has been with CATF since January 2010, focusing on methane from the oil and gas industries. David engages with industry, regulators, and researchers to better understand emissions sources and practices and technologies to reduce emissions. Recent and current collaborations include research projects to measure methane and other pollutants from well pads in Wyoming and Utah, emissions from flares in North Dakota, and volatile organic compounds in the Marcellus Shale production area of southwestern Pennsylvania. David has designed and managed studies of the feasibility of zero-bleed pneumatic equipment at oil and gas production sites; the economics of leak detection for oil and gas facilities; and alternatives to flaring of associated gas from shale oil plays. He has worked with multi-stakeholder groups such as STRONGER and the Center for Responsible Shale Development.
